Patent DE-3205368-A1 (DE)
Inventor: BRUNNER RUDOLF
IPC: F15B13/02
Filed: 1982-02-16
Abstract: The present invention relates to a flow divider for carrying out a load-independent division of a stream of hydraulic fluid, comprising a basic body including an internal bore, a central main connection and two outer consumer connections leading to said internal bore, and further comprising two approximately coaxial control pistons which are displaceably guided in said internal bore and which are each provided with a flow orifice and with at least one radial control opening, said control pistons being adapted to be moved towards each other and away from each other to a limited extent via a coupling device connecting said pistons. In the case of known flow dividers the coupling device consists of interengaging hooks which are rigidly formed on the control pistons, said hooks producing, however, eccentric forces for the control pistons in said internal bore, and said forces impair the control characteristics and the operating behaviour of the flow divider. The task is the provision of a flow divider in the case of which the control pistons can be displaced without any clamping forces being produced. In accordance with the invention, this task is solved by the feature that the support areas between the coupling device and the control pistons have a structural design similar to that of a ball and socket joint.
Patent DE-3205510-A1 (DE)
Title: Vibrating device
Inventor: IWAIDE TSUNEO
IPC: B06B1/16
Filed: 1982-02-16
Abstract: The vibrating device has a drive shaft, to which a first and a second eccentric body, each generating vibrations, are fastened. The second body is arranged next to the first and can execute a linear movement with respect to the first in a predetermined direction and transversely with respect to the drive shaft. By means of such vibrating devices, vibrations are exerted on the concrete to be compacted, said vibrations having a relatively large amplitude at the beginning of this work and during the use of a low rotational speed of the drive shaft. Thereafter, medium and higher rotational speeds are used, so that suitable lower amplitudes occur, as a result of which, overall, it is possible to achieve good precast concrete parts.

Title: Agents and processes for the separation of mixtures of solids
Inventor: PLEWINSKY BODO DR
IPC: B03B5/32
Filed: 1983-02-14
Abstract: Agents and processes are proposed for the separation of mixtures of solids, permitting mixtures of substances having components of differing density to be divided into their individual constituents rapidly, with low expenditure and virtually quantitatively. The separating agents used are solutions of metatungstates of differing concentration having densities up to 3.1 g cm<-3>. The process can be carried out either statically, that is using the earth's gravitational field, or using suitable centrifugal accelerations. Dense media of appropriate particle size can also be added as separating agents to the metatungstate solutions. Sodium metatungstate suspensions containing tungsten carbide, for example, give densities of 4.6 g cm<-3>.

Title: Method of controlling the strip thickness
Inventor: HERTLEIN KURT DIPL ING
IPC: B21B37/66
Filed: 1983-09-01
Abstract: In a method of controlling the strip thickness of rolled material running out of a roll stand, wherein the strip thickness h in the roll nip is determined indirectly according to the relationship <IMAGE> where s = roll setting, Fw = rolling force, 1/M = spring constant of the roll stand (gauge meter principle), periodical fluctuations in the strip thickness are to be detected completely and correctly, high absolute accuracy of the strip thickness measurement being achieved. This is achieved when the measured value of the strip thickness, determined directly by a thickness-measuring instrument downstream of the roll stand, is additionally delayed by a first running time term (T1), the additional running time being set as a function of the strip speed or roll rotation speed in such a way that the total of running time of the strip from the roll nip to the thickness-measuring instrument plus the additional running time is equal to the period of one revolution of the back-up roll, when the directly measured thickness value thus delayed, the indirectly measured thickness value and the indirectly measured thickness value delayed by a second running time term (T2), whose dead time corresponds to one revolution of the back-up roll, with a negative sign are summated, and that the deviation of these summated measured thickness values from a preset nominal strip thickness value is used, after control amplification, for adjusting the roll weighting or the strip tension.

Title: Rear rim for a tyre of a motor vehicle and method for its manufacture
Inventor: ENDO TAKURO
IPC: B60B21/00
Filed: 1983-12-08
Abstract: A rear rim for a tyre of a motor vehicle is produced from an elongate metal sheet by cold forming, the thickness of the elongate metal sheet being greater in areas which correspond to a flange or flanges of the rim than in areas of the elongate metal sheet which correspond to the base of the rim. The elongate metal sheet is then converted into an annular sheet with a cross-section of non-uniform thickness. This annular metal sheet is cold formed further in order to reduce the diameter of its central thin area which as a result forms the base of the rim and to enlarge the diameter of its thicker peripheral area which forms the flanges. The elongate metal sheet is formed in such a way that the thickness dimensions of the finished flanges and the base of the rim essentially correspond to one another.
